To all whom t may concem.'

Be it known that I, KARL citizen of Austria, residing at Braunschweig, Germany, have invented certain new and useful improvements in Centrifual Separatore for Pulpy Matter Such as rroundWood on Straw, Cellulose, and the like (for which l have iiled applications in Germany August 14:, 1922, and Austria l0 June 30, 1923), of which the following is a specication.

KLIMPKE, a

My invention relates to improvements in centrifugal separators for pulpy matter such as ground wood or straw, cellulose, and the 15 like, and more particularly in separators of the type in which thematter to be separated is supplied into a drum having its circumferential wall in the form of a sieve and comprising a rotary member provided with blades throwing the matter against the circumferential sieve. `In one type of apparatus of this class the matter flows into the` sieve in the form of a single current, and in another type it is discharged through a plurality of openings, so that it is uniformly distributed over the object of the improvements is to provide an apparatus of this type in which the matter is uniformly distributed over the area of the sieve, and in which obstruction of the discharge bythe matter is avoided. With this object inview my invention consists in constructing the discharge in the form of one or two overflows open at the top` andv extending substantially over the whole length of the drum. Preferablythe overflow or over- Hows are subdivided by ribs intor a plurality of sections each in the form of a. channel which is open at its top, and the channels extend to dilierent parts of the circumference of the drum.

For the purpose of explaining the invention an example embodying thesame has been shown in the accompanying drawing, in which the same letters of reference have been used in all'the views to indicate oorresponding parts. In said drawing,- Fig. 1, is 'an elevation of the separator, the sieve and the cylindrical wall enclosing the same being shown in section to illustrate the distributing member,

'improved se and loose pulleys k area of the sieve. The,

v formly discharged the distributer,

Fig. 2, is a longitudinal section of the separator,

Fig. 3, is a cross-section of the sieve, the rotary blades, and the distributing member taken on the line 3-3 of Fig. 2,

Fig. 4, is a similar cross-section taken on the line 4-4 of Fig. 2, and

Fig. 5, is another section taken on the line 5`5 of Fig. 2.

'In the example shown in the figures my arator comprises a pair of end plates a1 an a2 mounted on a suitable foundation, a cylindrical wall b connecting the same, a cylindrical sieve g secured to annular shoulders g1 of the end walls, a shaft c mounted in bearings al and carrying lixed and h1, a wheel carrying blades f* and keyed to the shaft c, and a distributing member e within the sieve and having an inlet e1. The end wall a2 is formed inner part of the sieve, and the cylinder b is provided with a discharge j communicating with the annular chamber provided between the wall b and the sieve g. a

The distributing member e is in the form of a trough which is'open at its top so as to provide two overfiows lc extending substantially over the whole length of the trough is formed with circumferential depressions Z1, Z1, Z2, Z2, and Z3, Z3 so as to provide channels separated by ribs n. and extending downwardly to different heights indicated by the letters m1, m2, and m3. l

In the operation of the apparatus the semi-liquid or pulpy matter is passed into the distributer e and it fills the same up to the overflows 7c, so that the matter is uniover the whole length of and the stream of the matter is divided into the channels Z1, Z2, Z3, said channels having the functions, first to prevent the parts of the stream to be again combined into a single stream, and second to diwith a discharge z' communicating with the rect the maftter to diii'erent parts of the cirmattei discharged from the channels Hows outwardly and towards the `blades which throw the same against the sieve. Therefore the mass of the matter is uniformly distributed over the whole circumference of the sieve. By providing overflows which are open at their tops the discharges can not be obstructed by the matter even if a large amount thereof is discharged.

While in describing the invention reference has been made to a particular example embodying the same, I wish it to be understood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and in the construction of its parts without departing from the invention. For example I do not limit myself to a construction in which a single distributing member is provided, or in which the mass of semi-liquid or pulpy matter is broken up internally of the sieve g. In some cases I divide the matter outside the sieve into separate streams and I conductI the same to separate overflows provided within the sieve g.

I claim: v

1. In an apparatus of the class described, the combination, with a sieve, and a rotary member mounted on a substantially horizontal axis and adapted to throw thematter to be separated against the sieve, of distributing means for supplying the matter to be separated to the rotary member and hav` ing an open overiiow for the discharge of the matter to the rotary member, said overflow being divided into sections adapted to divide the matter being discharged into separate streams.

2. In an apparatus of the class described, the combination, with a sieve, anda rotary member mounted on a substantially horizontal axis and adapted to throw the matter to be separated against the sieve, of distributing means for supplying the member and havin an open overflow for thevdischarge of t e matter to the rotary member, said overiow being divided into sections in the form of channels ending at different parts of the circumference of the sieve and adapted to` divide the matter being discharged into separate streams.

3. In an apparatus of the class described, the combination, with a sieve, and a rotary member mounted on a substantially horizontal axis and adapted to throw the matter to be separated against the sieve, of distributing means for supplying the. matter to be separated to the rotary member and having an open overflow for the discharge of the matter to the rotary member, said overflow being divided into sections in the form of channels ending at diHerent parts of the circumference of the sieve and adapted to divide the matter being discharged into separate streams, the bottoms of said l channels beino directed at their discharge ends outwardly and towards the rotary member.

zontal axis and adapted to throw the matter to be separated a ainst the sieve, Vof a distributing troughv aving an open overflow at its top for supplying the matter to be separated to the rotary member, said overflow being divided into sections in thefform of channels disposed circumferentially of the trough and ending 'at different parts of the circumference of the trough.

In testimony whereof I have affixed my signature. i
